High performance, compact size and low cost are the basic requirements of modern microwave communication systems. Various technologies have been developed to fulfill these requirements such as Substrate Integrated Waveguides (SIWs), Photonic Band Gap Structures(PBG), Defected Ground Structures (DGS), Electromagnetic Metamaterial structures and so on. Among these, Metamaterials are relatively new and the potential applications of these special classes of materials have drawn much attention in last few decades.

This book discusses the development of promising technologies for compact antennas for high data-rate communications. It discusses and analyzes the design of compact ultra-wideband (UWB) and multiple input, multiple output (MIMO) antennas, providing essential know-how for designers, practicing engineers and scientists. These wireless communication technologies enable consumers to have convenient access to a wide range of services – anytime, anywhere. And the introduction of wireless mobile access points eliminates the limitations to communication imposed by geographical location. The...
